Hiring employees in Connecticut: the 2026 compliance checklist for employers and recruiters

As of October 2026, an employer hiring in Connecticut has to register with the Department of Revenue Services for withholding and the Department of Labor for unemployment tax, carry workers' compensation, put the wage or wage range and a description of benefits in every job advertisement (new from October 1, 2026), keep age, date of birth, graduation dates and criminal history off the initial application, never ask about pay history, have each new hire complete Form CT-W4, give written notice of pay, hours and payday plus paid leave notices at hire, withhold the employee's Connecticut Paid Leave contribution, and report the hire to the Department of Labor within 20 days. Connecticut also limits credit checks and applicant drug tests, requires all-party consent to record phone calls under its civil law, and has AI hiring rules that phase in from October 2026.

The Connecticut hiring checklist at a glance

What must be in place before the first Connecticut hire?

Two registrations, an insurance policy and a payroll deduction. The Department of Revenue Services says a new employer "must register for Connecticut income tax withholding" through myconneCT, at no fee, and that employers "are also required to register with the Connecticut Department of Labor for unemployment taxes." The Workers' Compensation Commission says that "With few exceptions, all employers" in Connecticut must carry workers' compensation, out-of-state employers included for their Connecticut staff.

Connecticut Paid Leave is funded by employees. Under General Statutes § 31-49g, each employee contributes a percentage of earnings set by the Paid Family and Medical Leave Insurance Authority, capped at "one-half of one per cent," and the employer withholds it each payroll period and remits it to the program. The federal layer (an EIN, Form W-4 and Form I-9 by the third business day) applies on top.

Does a staffing or recruiting agency need a Connecticut license?

It depends on who pays. Under Chapter 564, an agency that charges job seekers a fee needs a license from the Labor Commissioner ($150 a year and a $7,500 bond under § 31-130(a)), while a placement or search firm paid only by employers registers with the same office for $150. A temporary help service that employs its workers and assigns them to clients is exempt from the chapter. Professional employer organizations register separately, and nurse staffing agencies have their own registration with the Department of Public Health. The administering office is the Department of Labor's Wage and Workplace Standards Division. See Connecticut staffing agency licensing for each track.

What must a Connecticut job posting include, and can you ask about pay history or age?

From October 1, 2026, the wage or wage range and a general description of benefits. Public Act 26-12 rewrote § 31-40z so that an employer may not "fail or refuse to disclose in an internal or public job advertisement" the wages or wage range and benefits for the position. It applies at any employer size and reaches remote roles that report to a Connecticut supervisor, office or worksite; for roles never advertised, the range is due at the applicant's request or before any discussion of compensation. See the Connecticut pay transparency guide.

The same section bars asking about wage and salary history, or having a recruiter ask, unless the candidate has volunteered it; you may ask about the elements of a pay package but not their value. See the Connecticut salary history ban. Age is off the initial application too: § 46a-60(b)(12), added by Public Act 21-69, bars requesting "age, date of birth, dates of attendance at or date of graduation" from a school on an initial application, unless needed for a bona fide occupational qualification or to comply with law.

When can you ask about criminal history or run a credit check?

Not on the initial application. General Statutes § 31-51i bars employers with even one employee, and their agents, from asking about prior arrests, charges or convictions on an initial employment application, and bars ever requiring disclosure of an erased record or rejecting someone solely because of one. A conviction question can come later in the process; see Connecticut's ban-the-box law, and run outside reports under the FCRA process.

Credit checks are limited by § 31-51tt: an employer may not require consent to a credit report as a condition of employment unless it is a financial institution, the report is required by law, it suspects specific job-related illegal activity, or the report is substantially related to the job, as with managerial roles, fiduciary duties, access to confidential or financial information, or a company card. Each violation carries a $300 civil penalty. Our credit check laws guide compares states.

Can you record or transcribe a job interview in Connecticut?

Get consent first, especially on the phone. Connecticut's criminal eavesdropping law, §§ 53a-187 and 53a-189, reaches only people who are not a party to the conversation. The civil statute, § 52-570d, is stricter for telephone calls: recording a private call is allowed only with the consent of all parties, a recorded verbal notice at the start, or an automatic warning tone, and anyone recorded otherwise can sue. Our Connecticut recording consent guide covers how that applies to video calls, and two-party consent states compares the rule elsewhere.

Does Connecticut regulate AI in hiring?

Yes, in two stages. Public Act 26-15 defines "automated employment-related decision technology" as technology whose output is "a substantial factor used to make or materially influence an employment-related decision." From October 1, 2026, using it is no defense to a discrimination complaint, and evidence of anti-bias testing may be considered. For deployments on or after October 1, 2027, a deployer doing business in the state must disclose when a candidate is interacting with the technology and give a written notice before the decision, and developers must give deployers what they need to comply. See AI hiring laws by state.

Can you drug test applicants in Connecticut?

Yes, with conditions. General Statutes § 31-51v lets an employer require a urinalysis drug test as part of the application process only if the applicant "is informed in writing at the time of application" of the employer's intent to test, a positive result is confirmed by a separate second test using gas chromatography and mass spectrometry or an equally reliable method, and the applicant gets a copy of any positive result. Results are confidential. Our drug testing laws guide compares other states.

Does Connecticut require E-Verify?

No. As of October 2026, no Connecticut statute, regulation or executive order requires private employers, state agencies, municipalities or state contractors to use E-Verify, and nothing limits an employer that enrolls voluntarily. The last mandate bill died in committee in 2010. Form I-9 is still required for every hire, and a federal contract can make E-Verify mandatory; see E-Verify requirements in Connecticut.

Which state withholding form does a new hire complete?

Form CT-W4, the Employee's Withholding Certificate, effective January 1, 2026, alongside the federal W-4. The form's employer instructions say that for any employee who does not complete it, the employer must withhold "at the highest marginal rate of 6.99%." Nonresidents who work partly outside Connecticut may also file Form CT-W4NA, and a copy of the CT-W4 can double as the new-hire report to the Department of Labor.

Which notices must a new Connecticut employee get at hire?

• Pay, hours and payday. § 31-71f requires every employer to "advise his employees in writing, at the time of hiring," of the rate of pay, hours of employment and wage payment schedule.
• Paid family and medical leave. § 31-49q requires written notice "at the time of hiring, and annually thereafter" of leave rights, the right to claim benefits, the ban on retaliation and the right to complain to the Labor Commissioner.
• Paid sick leave. Employers covered by § 31-57s (11 or more Connecticut employees in 2026, one or more from January 1, 2027) must give the § 31-57w notice at hiring.
• Disability accommodation. From October 1, 2026, section 31 of Public Act 26-12 requires written notice to new employees "at the commencement of employment" of their right to reasonable accommodation under the ADA; displaying the Labor Commissioner's poster satisfies it.
• Electronic monitoring. An employer that monitors employees electronically must give prior written notice under § 31-48d, which a conspicuous posting satisfies.

How do you report a new hire in Connecticut?

To the Department of Labor's state directory of new hires. General Statutes § 31-254(b) requires each employer maintaining an office or transacting business in Connecticut to report the name, address and Social Security number of each new employee "not later than twenty days after the date of employment," for example by forwarding a copy of the employee's CT-W4, with the employer's name, address and state and federal tax numbers. Employers reporting electronically send reports at least twice a month, 12 to 16 days apart. Independent contractors count when their services are expected to be worth at least $5,000 for the year, and multi-state employers may designate another state after notifying the Labor Commissioner in writing.

The Connecticut hiring steps in order

1. Before the first hire: register for withholding in myconneCT and for unemployment tax with the Department of Labor, bind workers' compensation, and set up Paid Leave contributions. Agencies that charge candidates get a license; employer-paid firms register.
2. Posting: wage or wage range and a benefits description in every internal and public ad from October 1, 2026.
3. Application: no questions about age, school dates, criminal history or pay history; tell applicants in writing if you will drug test.
4. Interview: get every party's consent before recording a call, and plan the 2027 notices if an automated tool influences decisions.
5. Offer: credit checks only within a § 31-51tt exception; confirm any positive drug test and give the applicant a copy.
6. First day: Form I-9, W-4 and CT-W4, the written pay notice, the Paid Leave, sick leave and accommodation notices.
7. Within 20 days of the date of employment: report the hire to the Department of Labor.
